Se presentan los números cromosómicos y la biología reproductiva de cuatro especies sudamericanas hexaploides (2n = 6x = 60) del género Andropogon. Las especies estudiadas pertenecen a la sect. Leptopogon Stapf (A. glaziovii Hack. y A. arenarius Hack.) y Notosolen Stapf (Andropogon sp. y A. glaucophyllus Roseng., B. R. Arrill. & Izag.). Este es el primer recuento cromosómico para Andropogon sp. y A. glaucophyllus. El análisis embriológico indica que las cuatro especies forman sacos embrionarios del tipo Polygonum var. Poaceae, reproduciéndose sexualmente. Los arreglos florales varían ligeramente: A. glaziovii y A. arenarius son principalmente andromonoicas s (h) + p(m) o hermafroditas s (h) + p (o). Andropogon arenarius y A. glaziovii son a...
